Each end of the U-shaped steel plate is provided with a wing plate, and the wing plate is bolted to the cross beam or purlin. The middle of the U-shaped steel plate is integrally connected to the L-shaped steel bracket. An exterior wall rabbet is provided at the end of the exterior wall panel for steel structure heat insulation, and the exterior wall rabbet seamlessly connects the upper and lower layers of exterior wall panels to the L-shaped steel bracket. The lower layer of the exterior wall panel is screwed to the L-shaped steel bracket at the exterior wall rabbet, and the upper layer of the exterior wall panel is placed on the L-shaped steel bracket. The U-shaped steel plate, the wing plate and the L-shaped steel bracket of this solution are assembled into an integrated component, which is directly processed and produced in the factory, simplifies the installation process of the steel structure exterior wall panel, shortens the installation time, avoids situations such as the falling off of the exterior wall panel, improves the connection strength, and the connection rabbet of the exterior wall panel enhances the embedding force between the panels, improves the safety of the connection of the exterior wall panel, and increases the firmness of the installation.

[0004] However, in the actual use process, the setting of the U-shaped steel plate increases the distance between the exterior wall and the main steel column (steel frame or inner wall), that is, it needs to occupy a larger external space, resulting in a reduction in the heat insulation effect and a waste of space. Content of the Utility Model

[0005] The purpose of the utility model is to provide a leak-proof installation structure for a steel structure exterior wall panel to solve the problem of space waste mentioned above.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A leak-proof installation structure for a steel structure exterior wall panel, installed on a steel frame, includes

[0009] A hanging plate, with a "7" - shaped cross-section, and the hanging plate is installed on the side of the exterior wall panel close to the steel frame. The vertical side of the hanging plate close to the exterior wall panel abuts against the vertical side of the purlin far from the exterior wall panel, and the bottom of the hanging plate abuts against the top of the horizontal side of the purlin.

[0010] Principle and effect of this technical solution:

[0011] 1. By mutually splicing and hanging the horizontal purlin with an inverted L-shaped cross-section and the hanging plate with a 7-shaped cross-section, the horizontal purlin can provide limit for the exterior wall panel through abutting against the hanging plate, making the installation and positioning of the exterior wall panel more convenient. Moreover, the horizontal purlin is located between the steel frames, and the projection of the hanging plate and the horizontal purlin on the horizontal plane coincides. Furthermore, the settings of the hanging plate and the horizontal purlin will not increase the distance between the exterior wall panel and the steel frame, that is, the space utilization of this solution is more reasonable.

[0012] 2. Through the assembly limit of the horizontal purlin on the hanging plate, after the exterior wall panel is hung on the horizontal purlin, it can maintain a certain stability, thus facilitating the user to adjust the position of the exterior wall panel. Furthermore, it is convenient to accurately position the exterior wall panel, and after disassembling and assembling the connecting parts, the exterior wall panel will not immediately fall down, with higher safety and facilitating subsequent maintenance and replacement.

Furthermore, the hanging plate can be adjusted in position relative to the steel frame, so as to avoid the steel frame and hang the hanging plate. Furthermore, the hanging plate can be used to hang and install the exterior wall panel for steel frames with various size spacings, thus improving the adaptability of this device, and the sliding bar is detachably installed with the exterior wall panel, so that the specific position of the sliding bar can be adjusted according to the actual situation.

[0015] This utility model is further configured as: the ratio of the length of the sliding bar to the length of the exterior wall panel is less than 1:2.

[0016] Principle and effect of this technical solution: By restricting the length of the sliding bar relative to the horizontal purlin, the position and quantity of the sliding bar relative to the exterior wall panel are more flexible, that is, the position and quantity of the sliding bar can be adjusted according to the position of the steel frame, etc., so as to ensure that the hanging plate can be hung on the horizontal purlin, so that the structure of this solution can adapt to steel frame structures with various sizes.

[0017] This utility model is further configured as: the width of the sliding bar and the width of the hanging plate are both not greater than the width of the horizontal purlin.

[0018] Principle and effect of this technical solution: By restricting the widths of the sliding bar and the hanging plate, the setting of the sliding bar and the hanging plate will not increase the distance between the exterior wall panel and the steel frame, thus avoiding excessive occupation of space.

[0019] This utility model is further configured as: The tongue-and-groove includes a male tenon located at the top of the exterior wall panel and a groove located at the bottom of the exterior wall panel. The cross-section of the male tenon is in a "concave" shape. A notch is provided on the side of the male tenon away from the steel frame. The groove is adapted to the male tenon, and a convex edge is provided on the side of the groove away from the steel frame. The convex edge is spliced with the notch, and the top surface of the notch is lower than the bottom surface inside the male tenon.

[0020] Principle and effect of this technical solution: Due to the "concave" cross-section of the male tenon and the setting of the notch, when the groove and the convex edge of the upper-layer exterior wall panel are spliced with the male tenon and the notch of the lower layer, the splicing seam is more complex, and it is more difficult for water flow, etc. when it rains outside to enter the inner side of the exterior wall panel through the splicing seam, thereby improving the waterproof effect.

[0021] This utility model is further configured as: It further includes a reinforcing member and a self-drilling screw. The cross-section of the reinforcing member is in an "L" shape. The reinforcing member is arranged at the notch. The end of the self-drilling screw passes through the reinforcing member and the side wall of the notch and is threadedly inserted into the steel frame.

[0022] Principle and effect of this technical solution: By arranging the reinforcing member at the notch and installing the exterior wall panel on the steel frame through the self-drilling screw, when the upper-layer exterior wall panel is spliced on the lower-layer exterior wall panel, the convex edge can block the reinforcing member and the head of the self-drilling screw, thus avoiding the situation of the decline of the heat preservation and protection effect caused by the exposure of the self-drilling screw to the outside and rusting, accelerating aging, etc. And through the setting of the reinforcing member, after the self-drilling screw drills a hole in the exterior wall panel, the influence of the outside on the exterior wall panel at the hole is smaller, protecting the exterior wall panel.

[0023] This utility model is further configured as: The horizontal purlin is an angle steel purlin.

[0024] Principle and effect of this technical solution: It is an existing engineering material, which is easier to purchase and process, and thus has a lower cost. BRIEF DESCRIPTION OF THE DRAWINGS
